DISH-WASHIN' G MACHINE.

. Specification of Letters Patent.

Patented Apr. d, 1916.'

Application led October 14, 1915. Serial No. 55,750.

To all inkom', 'it may concern.' l

Be it known that I, WILLIAM CAMPBELL,

'ya citizen of the United States of America,

residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Dish- Washing Machines, ofv which the follpwing is a specification, reference being had therein to the accompanying drawings.

This invention relates to'a dish washing machine, and the primary object of my invention is to provide a novel washing ina-y chine which may lbe utilized as akitchen table, even while the machine is in operation, the kitchen table being convertible into a ldish washing machine by simply raising a movable top' section of the table, placing dishes in the machine, and thenfplacin the machine in operation. This object o my invention is attained by a strong and Fdurable structure possessing sufficient rigidity to permit of the top of the machinebeing used for various purposes -and particularly asa table top.

Another object of my invention is to place an electrically operated washing and rinsing machine below the top of a table whereby itv will occupy a comparatively small space in a kitchen or culinary department and permit oughly washed and rinsed when occasion requires. This object is attained by a washing machine embodying a suitable casing having a-drain board or bottom terminating in a basin, and in the basin is means for agitating the contents thereof and projecting the contents upon dishes and utensils placed within the-casing. y

A further object of my 'invention is to provide a combined kitchen table and washed with a view of reducing the cost of manufacture and atthe lsaine t' features by jwhich the parts ofthe machine maybe easily assembled and economically operated.

With the above and other objects in view, the invention resides in the-.novel construction, combinationand arrangement lof parts to be hereinafter speciiically described andthen claimed, and 'reference will now be had to the drawings, wherein- Figure 1 is a longitudinal sectional View of a dish washingy machine in accordance with my invention; Fig. 2 is a horizontal sectional/ view taken on the line II--II of v2 are connected ing machine wherein the parts `are constructme retaining those Fig. l; Fig. 3 isa front elevation of the dish washing machine; Fig. 4 is a cross sectional view taken on the line IV*IV of Fig. 3, showing the lid or closure of the machine in a raised position and partly broken away, and Fig. 5 isv an enlarged detail sectional view of a. bearing, illustrating a packing for the same.

In describing my'invention byl aid of the views above referred to, I desire to point out that -the same are merely lillustrative of an example whereby my invention may be applied in practice, and I doiiot care to confine the invention tothe preciseconstruction and arrangement ofparts shown. The following descriptionis therefore to be broadly construed as including substitute constructions and arrangements of parts which are the obvious equivalent of those to be hereinafter referred to.

' In the drawings, 1 and 2 denote sets of legs or uprights preferablyl made of angle iron, and the upper ends of the 'legs 1 aid by longitudinal side frames 3 and 4, also made of angleiron.

Suitably connected to the lateral anges I I of the frames 3 and 4 contiguous to the legs 1, is a permanent top section 5 1n the .form of a board, incased-in a metallic sheeting 6 which protects the board and .presents a`r surface that cannot be easily injured when meat or vegetables are cut upon the top section or hot., utensils placed thereon. The permanent top section has its longitudinal edges equidistant from the legs 1, thereby overhanging one end of the rectangular T" structure formed by the legs 1Y and 2 and the side frames 3. y

Extending toward the legs 2 are bearing members 7, carried bythe legs 1 and connected tov said bearing members, the legs 2 andthe side frames 3,-are the side .walls 8 of substantially arectangular 'metallic casing, said .casing having an open top, a vertical end wall 9, an inclined -end wall or deiiector 10, an inclined drainboard orbottom 11, and a transverse semicylindrica-l basin 12 at the lower edge of the drain bottom or l.board 11. The inclined endwall 10 is disposed at a tangent relative'to the basin 1 2 and the upper e verse ange 14 securedA to the edge or underside of the permanent top section 5.

' Hinged or otherw-ise connected to theside ,frame 3, as at 15, is a movable top section 16 ge of said inclined. wall is offset, as at 13, and provided with a transserving functionally as ahlid or closure for the casing, and when closed, as a continuation of the permanent top'section 5, whereby these two sections will coperate in p roviding a table top just as useful if not more so than the ordinary kitcheh table top. The movable top section 16 is incased by a metallic sheeting 17 formed at the inner side of the movable top section to provide flanges 18 adapted to engage the inner sides of the walls 8,9 and 10 and correctly position the movable top section when closed. When the movable top section 16 is open, its opening movement is limited b v a stop member .19 carried by the overhaging edge of the movable top section, as best shown in Fig. 4, said stop member preventing the movable top section from injuring a wall or swinging so far open that it cannot be conveniently closed from the front side of the machine.

The confronting sides of the walls 8 of the casing are provided with inclined angle brackets 2O adapted to support a wire tray 21 or a foraminous holder for dishes or utensils. The inclined bottom or drainboard 11 of the casing is also ada ted to support a wire tray or foraminous ho der 22 constructed and'partitioned for holding various kinds of dishes or utensils, whereby the surfaces 0f the dishes or utensils ,may be subjected to a washing or rinsing'action. For instance, the tray or holder 22 has receptacles or ca es 23, formed of wire or perforated metal y which spoons, knives, forks or other culinary implements may be supported and subjected to a washing or rinsing action.

Journaled in the bearin members 7 is a driven shaft 24 disposed ongitudinally of the basin 12 and mounted upon said shaft, within the basin 12,l is an agitating and projecting-two-blade member 25, said member having the longitudinal outer edges thereof disposed at an angle, as indicated at 26, whereby water or a cleansing liquid within the basin 12 will be projected against the inclined wall 10. An end of the driven shaft 24: protrudes from the rear side of the machine and is provided with' a large grooved wheel 27 for a belt 28 ,trained over a small pulley 29 on the armature shaft ofan elec-v tric motor 30 secured to a bracket 31, carried `by the leg 1 at the rear side of the machine."

A, switch 32 controls the operation -of the mbtorBO and said motor may be operated by air' ordinarly any suitab e source of electrical ener The basin 12, at the forwardend t ereof, has a drain or outlet port 33 normally closed bya plug a rod 35. The rod 35 is ofset to provide clearance for the driven shaft '2f and said? rod extends through ajtube 36, carried by the inclined wall 10 of the The upper endvof the rod 35 is loosely connected to 37 on a lshaft 38, journaled ln'a secy acrank electric lighting circuit or from or stopper 34 on the lower end of tor bearing 39 carried by the leg 1 at the front side of the machine. The shaft 38 has an operating handle or crank 40 in frictional enga ement with thesector bearing 39 and by a justing the handle 40 the plug or stopper 34 may be raised and lowered.

To insure a non-leakable connection between the driven shaft 24 and the rear wall of the casing, said shaft has a packing collar 41, as best shown in Figs. 1, 4 and 5, said collar snugly fitting the driven shaft and reventing water or washing liquid from eaking through the bearingv of said shaft.. V

To place the machine in operation, the

vmovable top section 17 is raised, trays of lower part o the casing, the water is projected on to the dishes within the trays or holders 21 and 22 and after this operation has been carried on for a predetermined time, the water can be removed from the basin 12 through the drain or outlet port 33 and a fresh supply of waterv placed within the casing for rinsing the dishes therein.

I attach considerable importance to the inclined' drain board and bottom 11 and the basin 12 of the casing, as all water and matter drains into the basin and the water may be removed or repeatedly used. The-basin however is-of such depth as to collect foreign matter and it is possible to .thoroughly cleanse and iiush the basin after 'the washin machine hasbeen used.

e inclined end wall 10 coperates with the member 25 inl projecting water or a washing solution over the dishes, and when a washlng powder or a suitable detergent is used in the water the member 25 causes the detergent to thoroughly commingle with the water'.

, Ordinarily a receptacle is placed beneath the drain lor outlet port 33 of the basin 12 to receive -water f' therefrom, after the machine has been used, but in some instances a yhose may be attached to the drain or outlet port to .conduct the contents of the-basin direct large'protected area that may be used simlj.

l I claim"1s: A duh washing machine comprising a larll to an ordinary kitchen table top..

. basln forming part of ing a drain port at an end thereo a stop er for the basin drain port, a Jrod dp to frame, a top section sup orted thereby, a casing supported by said frame and having an inclined wall extending inwardly from one end of said frame to said top section,
